Crankshafts – Cummins, Caterpillar, J Deere…
Premium forged crankshafts to suit Cummins (most models), Caterpillar 3408, 3412 (& many other models), Detroit S60, Mack E6, E7, J Deere, CaseIH, Navistar.
Crankshaft as the word suggests, converts reciprocating action created by the combustion process into rotational motion for power output. Catamac stocks the finest state-of -the-art engineering imported direct from the manufacturer for the Australian & South Pacific engine building industry.
In production the white hot premium steel billet is forged then primary turned on an orbital milling machine. Further manufacturing processes include automatic oil hole and flange drilling/threading, induction hardening/tempering and radius rolling of journal fillets, finish grinding/polishing, balancing and preservax coated for shipping and storage. Working to very fine tolerances, shafts are laser checked dimensionally, surface finish, magna and durometer tested. The finished product, a precision crankshaft many of which are used in a spread of American diesel engines in Australia during the last 18 years. The manufacturer also supplies to a number of world renown OEM’s.

Damper – Crankshaft Vibration Damper
The crankshaft damper (also referred to as dampener, harmonic balancer, viscous damper etc) is a purpose built device which absorbs torsional vibrations created from the combustion process and transferred via piston and connecting rod to the crankshaft journal.
The rubber separation type is made from an inner and outer steel core separated and vulcanized with rubber. The viscous damper comprises an outer steel housing and an inner inertia ring separated by silicone fluid, and is a completely sealed non-serviceable unit.
It is important that crankshaft dampers are replaced every 800,000K’s or 15,000hrs as a minimum. The damper should always be replaced when a new or replacement crank is installed.
